Abstract
A circularly polarizing plate capable of suppressing occurrence of light leakage at a corner portion in a display device and suppressing the corner portion from being conspicuous in a reflected image when the circularly polarizing plate is used in a self-luminous display device in a high-temperature and changing humidity environment; and a self-luminous display device. The circularly polarizing plate includes, in order, a retardation layer, and first and second light-absorbing anisotropic layers, where a support is not provided between any of the three layers; the first light-absorbing anisotropic layer has an absorption axis in a plane of the first light-absorbing anisotropic layer; an angle θ between a transmittance central axis of the second light-absorbing anisotropic layer and a normal direction to the second light-absorbing anisotropic layer surface is 0° or more and 45° or less; and a thermal shrinkage force of the circularly polarizing plate is 5 N/m or less.
